The first place to start is with BMR (Body Mass Ratio), strength and overall riding fitness.

The bottom line is, it's a total weight package which includes CofG (Center of Gravity) and Neutral Point for stability management and this includes the rider too as they are the largest weight load component..

Had lengthy discussion with friend about if it was worth spending the money to shed 10lbs off our bikes.....after several beers we decide it would be cheaper and better to just lose the weight from our mid-sections.

You just can't believe how much faster my two bikes are since I lost 40 lbs in the past year.
Nuff said! Mo report time.
